Human eye lenses block ultraviolet light, but animal eyes with UV-transparent lenses let ultraviolet light reach the retina, which converts the light into nerve signals that travel to the brain where the visual system perceives them. Humans can only detect colors from red to violet; cats and other that see in ultraviolet see a broader range of color.
